[Lubuntu] No pulseaudio explains no local sound on LTSP clients?

[Aere Greenway]

John:

If I could have remembered anything of how do do it, I would have passed
it on.  

It seems I saw something in an Ubuntu forum about configuring Pulseaudio
on Lubuntu.  

I did a Google search just now for "pulseaudio lubuntu", which came up
with interesting stuff, but not what I remembered using.  

I did see this one piece of information that seemed familiar:


Re: No audio lubuntu 12.04

Be sure that pavucontrol, pulseaudio, pulseaudio-utils and libgtk-3-0
are all installed. Then play with the different settings in pulseaudio
volume control and the controls in your player until you get sound.

That seems to be what I did, that finally got it working.  

I also had issues with having two soundcards on my machine, where
sometimes they would initialize in the wrong order, and I would get no
sound because it was using the soundcard with no amplifier/speakers
hooked to it.
